Abstract: A method to drive bi-stable liquid crystal displays and related drivers and displays using same are disclosed. The method and driver use additional high impedance states of the outputs to save power while addressing bi-stable and multi-stable liquid crystal displays. The invention implements high impedance states at the driver outputs, allowing non-addressed sections of the display to electrically “float” and by doing so reduces the required power to drive the display. Other advantages include improved visual effect of an update, such as reduced flash during the update, simpler operation, and better yields due to a larger operating window.

The device is at least partially inserted along an axis of insertion. The reservoir enlarges from an insertion configuration having a first three-dimensional shape to an expanded configuration having a second three-dimensional shape, the second three-dimensional shape being eccentrically positioned relative to the axis of insertion.

Abstract: Bright ambient light can wash out a virtual image in a conventional augmented reality device. Fortunately, this problem can be prevented with a variable electro-active beam splitter whose reflect/transmit ratio can be varied or switched on and off rapidly at a duty cycle based on the ambient level. As the ambient light gets brighter, the beam splitter's transmit/reflect ratio can be shifted so that the beam splitter reflects more light from the display and transmits less ambient light to the user's eye. The beam splitter can also be switched between a highly reflective state and a highly transmissive state at a duty cycle selected so that the eye spends more time integrating reflected display light than integrating transmitted ambient light. The splitting ratio and/or duty cycle can be adjusted as the ambient light level changes to provide the optimum experience for the user.

Abstract: The disclosed calibration method includes a calibration phantom positioned on an adjustable table on the surface of a mechanical couch, with the phantom's centre at an estimated location for the iso-centre of a radio therapy treatment apparatus. The calibration phantom is then irradiated using the apparatus, and the relative location of the center of the calibration phantom and the iso-centre of the apparatus is determined by analyzing images of the irradiation of the calibration phantom. The calibration phantom is then repositioned by the mechanical couch applying an offset corresponding to the determined relative location of the centre of the calibration phantom and the iso-centre of the apparatus to the calibration phantom. Images of the relocated calibration phantom are obtained, to which the offset has been applied, and the obtained images are processed to set the co-ordinate system of a stereoscopic camera system relative to the iso-centre of the apparatus.
